Abstract
This review is devoted to analysis of the possibility to use electrochemical energy systems at low temperatures. It is not possible to attain this goal without ecologically pure autonomous energy sources – chemical current sources capable of operating at temperatures up to –60 °C which are presently under development. Renewable energy systems combined with hydrogen fuel cells can also be used for this purpose, in particular with fuel cells and solid polymer electrolyte that can already operate normally at temperatures ranging from -20 to +50 °C and are perspective to be used and stored at lower temperatures.
